求编译器源代码

如题，编译过程按网上说的那样，但编译时出错：
net/netfilter/xt_layer7.c:417: warning: ‘struct xt_match_param’ declared inside parameter list
net/netfilter/xt_layer7.c:417: warning: its scope is only this definition or declaration, which is probably not what you want
net/netfilter/xt_layer7.c: In function ‘match’:
net/netfilter/xt_layer7.c:434: error: dereferencing pointer to incomplete type
net/netfilter/xt_layer7.c: At top level:
net/netfilter/xt_layer7.c:616: warning: initialization from incompatible pointer type
net/netfilter/xt_layer7.c:617: warning: initialization from incompatible pointer type
make[3]: *** [net/netfilter/xt_layer7.o] 错误 1
make[2]: *** [net/netfilter] 错误 2
make[1]: *** [net] 错误 2
make[1]:正在离开目录 `/usr/src/linux-2.6.35.9'

求高手解决！
